Question

Android Broadcast 怎么不被其他应用接收

Answer 1

以下符合你要求的动态广播：

发送广播：
Intent i = new Intent();
i.setAction("ACTION_CLOSE");
sendBroadcast(i);

接受广播：
onCreate(){

//注册广播的接受者
IntentFilter filter = new IntentFilter();
filter.addAction("ACTION_CLOSE_ACTIVITY");
receiver = new InnerReceiver();
registerReceiver(receiver, filter);
}

private class InnerReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
//TODO 当前Activity接收到广播 需要做的事情
}
}
}

//注销广播

@Override
protected void onDestroy() {
super.onDestroy();
unregisterReceiver(receiver);
}
